Stratigraphy
Stratigraphic resolution:bed
Stratigraphy comments: The base of the Mirador is drawn at the level where the sandstones of the formation rest on the claystones or siltstones of the Los Cuervos. The contact is easily recognized and is, at least locally, unconformable. The Mirador/Los Cuervos contact represents a major change in sedimentation for the region, as it marks the appearance, at higher levels than the Uribante, of abundant, coarse, 'clean' sandstones give way to grey, micaceous, and in part sandy, shales which form the lowermost sediments of the overlying Carbonera Formation.
Lithology and environment
Primary lithology:massive,fine,coarse lithified conglomeratic sandstone
Secondary lithology:lenticular,brown lithified argillaceous "shale"
Lithology description: The Mirador Formation is predominantly composed of sandstones. These are pale buff to white, characteristically pure, massive, moderately hard to friable, fine- to coarse-grained, and in part conglomeratic. It contains some thin beds of grey and brownish-grey micaceous shale. An interval of shale and sandy shale with a little sandstone commonly occurs 40 to 75 meters below the upper level of the formation and ranges between 10 and 70 meters in thickness. The sandstones in the lower part of the formation tend to be more thinly bedded and less 'clean' than the bulk of the formation.
Environment:fluvial-deltaic indet.
Taphonomy
Modes of preservation:soft parts,original sporopollenin
Size of fossils:microfossils
Temporal resolution:time-averaged
Collection methods and comments
Reason for describing collection:biostratigraphic analysis
Collection method comments: From each coal or lignite layer several individual samples were analyzed, or the results of several samples were pooled.
